Ludwig's WRAP-UP

In summary, the phrase "this study primarily on" is grammatically incorrect because it is missing a verb. As Ludwig AI points out, the construction needs a verb like "focuses", "relies", or "is based" to properly connect the subject (the study) with its primary focus. The corrected phrase is most commonly found in science-related contexts. Related phrases, like "this study focuses mainly on" or "this study's primary focus is on", offer grammatically sound alternatives. Remember to include a complete verb phrase to clearly define the main subject of your study. The phrase, even if not grammatically correct, has a communicative purpose for indicating what are the primary areas or topics in the research. Thus, always ensure to use complete and well-structured phrases to maintain clarity.

FAQs

How to correctly phrase the focus of a study?

Instead of "this study primarily on", use phrases like "this study "focuses on"", "this study "concentrates on"", or "the primary focus of this study "is on"".

What is wrong with the phrase "this study primarily on"?

The phrase "this study primarily on" is grammatically incomplete. It needs a verb to connect the subject ("this study") to its object. Adding a verb such as "focuses" or "relies" corrects the phrase.

What can I say instead of "this study is primarily on"?

Consider using "this study "primarily focuses on"", "this study "is mainly about"", or "this study "chiefly concerns"" as alternative ways to express the study's scope.

How does the meaning change if I use "this study focuses on" instead of "this study primarily on"?

Adding "primarily" emphasizes that the focus is mainly, but not exclusively, on the specified subject. Removing "primarily" with "this study "focuses on"" suggests the focus is solely on that subject. The presence of "primarily" leaves space to interpret that there is more content in the study but it is not the main target of it.
